I posted a vid testing a PACBRAKE PRBX valve in my shop. Nothing being hidden here:) I am going to put it down where the joint is located at the muffler inlet. its a little less cluttered/crowded there than up at the turbo outlet, especially considering my altered intake routing to get the...

All weather pen, MRE Tabasco bottle and some chapstick:) For oil return, there should be a plugged port just above the oil pan lip along the block, and cat put dipstick ports in all 4 corners…

Yep, thats the procedure to access and check/tighten them

Pull your bottom cover on the bellhousing and check the TC mount bolts…

Yea I think it is standard national pipe. Yes, flex plate bolt access…

If you move the tailpipe venturi to the vertical exhaust stack? I would think it should still work OK. If the vacuum flow is enough to pull the particulates horizontally across the particle separator gallery it should have no problem to eject them out the pipe as high vac is caused by high...

If its what I am thinking of, a single director that pulls air in around the peripheral of the air filter housing and a place for dust to fall out to a catch point at the end is a common item on tractors. The one on the LMTV is a little different. It has a series of smaller high velocity...

Its not an exhaust gas return. Note how the tailpipe is crimped in where that tap is located? The tap goes into the pipe and turns down stream into the crimped area. Thats a Venturi and creates a vacuum on that line. It is connected into the middle of the particle separator module above the...

Well the original scope of this thread was discussing deleting CTIS completely. And putting a schrader core in the wheel stem. In that case the banjo is unnecessary and is replaced by a standard 5/8 fine thread bolt inserted to fill the hole in the hollow stud. now if you are talking about...

Yep, It does matter as the base power for the flasher module for use by the turnsignals is provided by the hazard normally closed contacts when in the hazard off position. When you select hazard on, it provides power from a different source, but one that still must be authorized by the...

Yep, seal washer and bushing on either side of the ujoint(outer end of axle housing/inner end of spindle tube) IMO if you are going to pull the hub down to the point where you can access that inner spindle bushing and seal, you can pull the axle shaft, overhaul the ujoint and do at a minimum...

Exactly! I have never seen topically applied RTV seal anything, except the moisture inside the connection:)

well if you had high-beams selected/on when it was cycling, the dash high-beam indicator would cycle with the headlights going on and off, either caused by the light switch or by K-07 cycling... Did you jumper 30-87 on K-07? that will effectively bypass the light switch and test all the other...

Here, this should be a little easier to follow…

Pull relay K07 and install a jumper wire with 1/4” spade terminals between pin 30 and 87 in the relay socket. This will turn on your headlights and take the light switch out of the equation for testing. If the lights work ok this way, pull the jumper and move relay K20 to the K7socket and use...

point it down:)

Looks like you could hang a snowplow off of it:) Is that blue line running across the front of the engine the makeup line from the expansion tank?

In place of a rubber cover, the rtv keeps a dropped wrench from arc welding itself in place. Not needed on the ground stud though, only the + terminals on the solenoids and starter motor… later A1 trucks added the battery disconnect relay and the LBCD to control it/ disconnect the load/batts...

The battery ground lead cable runs to a stud on the front of the starter motor housing. From that stud there is a braided strap over to the drivers frame rail. That is how battery ground reaches the rest of the chassis… voltage drop tests can be run on all these circuits if you have a battery...

Have you cleaned the connections on the polarity box/LBCD back by the spare tire? How about ground strap between starter and drivers frame? the alt relies on a good connection between alt and batt, all 3 of them, 12, 24 and gnd…
